wasmtime: update to v39.0.1

[leonm1]

Release notes: https://github.com/bytecodealliance/wasmtime/releases/tag/v39.0.1

The original goal:

• Allow wasmtime to instantiate AOT precompiled wasm modules (e.g. with wasmtime compile).
• Update wasmtime to a recent version for performance testing.
• Add resource limiting to bring it to parity with V8.

In order to make the resource limiting changes, I needed to use the wasmtime C api rather than the wasm-c-api. I migrated the wasmtime implementation to use the C++ API and migrated the C-api to use the prefixed version by default (required to use the C++ API).

Other yak shaving changes required to make this change:

1. Update rules_rust to use a more recent rust toolchain required by wasmtime.
2. Update platforms, rules_cc, and bazel to permit a more recent rules_rust
